Lloyd Industries 55CRDEA14 Ceiling Radiation Damper 14in

Product Description

The LLOYD INDUSTRIES 55CRDEA14 is a 14-inch round ceiling radiation damper rated for 3-hour fire resistance. Ceiling radiation dampers are installed at light fixtures, grilles, or other ceiling penetrations in fire-rated floor-ceiling and roof-ceiling assemblies. They automatically close when exposed to elevated temperatures, stopping the transfer of radiant heat through the ceiling membrane. This damper is designed to maintain the integrity of the fire-rated assembly in which it is installed. Licensed HVAC technicians and fire-life-safety contractors are the typical installers for this type of component.

This unit is suited for residential and commercial construction projects where fire-rated ceiling assemblies require compliant penetration protection. Typical applications include wood-frame multi-family buildings, hotels, and healthcare facilities where building codes mandate ceiling radiation dampers at HVAC and lighting penetrations in rated assemblies. The 14-inch round profile matches standard round duct and grille openings of the same diameter.

Key Features

• 3-hour fire-resistance rating for use in rated ceiling assemblies
• 14-inch round configuration fits standard round ceiling penetrations
• Automatic closure mechanism activates under elevated heat conditions
• Designed for installation in fire-rated floor-ceiling and roof-ceiling assemblies
• Supports code compliance for penetration protection in commercial and residential construction

Compatibility

Designed as an OEM-style ceiling radiation damper for use in 14-inch round penetrations within fire-rated ceiling assemblies where a 3-hour rated damper is required.

Installation Notes

Ceiling radiation dampers must be installed by a licensed HVAC or fire-life-safety contractor in accordance with the International Mechanical Code and applicable local building codes. Power down all associated HVAC equipment and de-energize lighting circuits before beginning installation at the ceiling penetration. Follow the manufacturer's listed installation instructions precisely, as improper installation can void the fire rating. The completed installation is typically subject to inspection by the authority having jurisdiction.
